Professional Liability Insurance in Canada
Also called errors and omissions (E&O) insurance. If a client says your advice, design or service cost them money, professional liability insurance is the policy that responds.


What is professional liability insurance?
Professional liability insurance, also called errors and omissions (E&O) insurance, pays when a client claims that your advice, design or service cost them money. It responds to claims about the quality of your work, not to injury or damage to property.
Even a claim without merit costs money to defend. That is what this coverage is built for, and it is why consultants, freelancers and licensed professionals are often asked to carry it before a client signs a contract.
Who needs professional liability insurance?
Anyone who gives advice, designs something or delivers a service where a mistake could cost a client money. A good test: if a client could argue that your work, not just your product, caused them a loss, this coverage is relevant to you.
What does a real claim look like?
These examples are illustrative, not real cases. In each one, the cost of defending the claim is what the policy is built to pay for, whether or not the claim succeeds.
Professional liability vs general liability
They cover different risks, and many businesses need both.
| Professional liability | General liability | |
|---|---|---|
| Covers | Claims that your advice, design or service cost a client money | Bodily injury or property damage you cause to others |
| Example | A consultant’s plan fails and the client sues to recover the spend | A customer slips in your office and is injured |
| Commonly needed by | Consultants, designers, IT and licensed professionals | Most businesses that deal with the public or work on others’ property |
For the other half of the picture, see general liability insurance.
How much does professional liability insurance cost?
There isn’t one price. What you pay depends on what you do, how much you earn and how much protection you want. The only reliable number is a quote for your own business, and Clearly Rate doesn’t set prices. The insurer does.
What affects the price
- Your profession and the services you offer
- Annual revenue
- The limit and deductible you choose
- Your claims history
- The contracts you sign, which sometimes require a minimum limit
- How long you’ve been in business
How to keep your premium down
Describe your work accurately, since gaps between what you do and what you told the insurer can cause problems at claim time. Choose a limit that matches your contracts and the size of your projects. Ask what a higher deductible would save, and whether you’re comfortable paying that amount yourself.
Is professional liability insurance required?
No general law requires it, but you’re often required to have it in practice.
| Situation | What’s usually required |
|---|---|
| You sign contracts with clients | Many contracts set a minimum limit and ask for proof of cover before work starts |
| You work in a regulated profession | Your regulator or professional body may require it, or run its own program |
| You work for larger organizations | Procurement teams commonly ask for proof of professional liability insurance |
What professional liability insurance doesn’t cover
Professional liability responds to financial-loss claims about your work. It isn’t a catch-all. It generally won’t cover:
- Bodily injury or property damage, which falls under general liability
- Intentional wrongdoing, fraud or criminal acts
- Disputes over fees you’re owed, on their own
- Data breaches, which usually need a separate cyber policy
- Problems you already knew about before the policy started
- Promises in a contract that go beyond your normal legal duty, such as guaranteeing a result
Exclusions vary by insurer, so read the list before you buy.
How a claim gets handled
Claims-made cover
Most professional liability policies are written on a claims-made basis. That means the policy has to be in force when the claim is made, not only when the work was done. If you let a policy lapse, a claim about past work may not be covered. Ask about the retroactive date, which sets how far back your work is covered, and what happens if you close your business or retire.
